This is a small microbit game consisting of 4 puzzles.
I use this puzzle when introducing the Microbit for the first time. Students have to figure out all solutions themselves, and the fastest ones get a prize (such as a chocolate bar).
The intent is for students to get an idea of some of the possibilities with the Microbit. For this reason, the puzzles use a bunch of the Microbit's abilities: text, animations, buttons, and gestures (should also include accelerometer usage in the future).
Once they have a good idea of the capabilities, they should be more motivated to create their own programs, and will have a better idea of what's possible to build. (Additionally, the code can also serve as an example or a starting point for them.)
Either copy the code to the online MicroPython editor, or use directly the .hex file.
This program is at the limit of the Microbit's memory usage. In order to add more content, you will likely have to remove some.
